MAX4310–MAX4315
The MAX4310–MAX4315 single-supply mux-amps com-
bine high-speed operation, low-glitch switching, and excel-
lent video specifications. The six products in this family are
differentiated by the number of multiplexer inputs and the
gain configuration. The MAX4310/MAX4311/MAX4312 inte-
grate 2-/4-/8-channel multiplexers, respectively, with an
adjustable gain amplifier optimized for unity-gain stability.
The MAX4313/MAX4314/MAX4315 integrate 2-/4-/8-chan-
nel multiplexers, respectively, with a +2V/V fixed-gain
amplifier. All devices have 40ns channel switching time
and low 10mVp-p switching transients, making them ideal
for video-switching applications. They operate from a sin-
gle +4V to +10.5V supply, or from dual supplies of ±2V to
±5.25V, and they feature Rail-to-Rail
®
outputs and an input
common-mode voltage range that extends to the negative
supply rail.
The MAX4310/MAX4311/MAX4312 have a -3dB bandwidth
of 280MHz/345MHz/265MHz and up to a 460V/µs slew rate.
The MAX4313/MAX4314/MAX4315, with 150MHz/127MHz/
97MHz -3dB bandwidths up to a 540V/µs slew rate, and a
fixed gain of +2V/V, are ideally suited for driving back-
terminated cables. Quiescent supply current is as low as
6.1mA, while low-power shutdown mode reduces supply
current to as low as 560µA and places the outputs in a
high-impedance state. The MAX4310–MAX4315’s internal
amplifiers maintain an open-loop output impedance of only
8Ω over the full output voltage range, minimizing the gain
error and bandwidth changes under loads typical of most
rail-to-rail amplifiers. With differential gain and phase errors
of 0.06% and 0.08°, respectively, these devices are ideal
for broadcast video applications.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
